If Earth orbited WISE J085510.83-071442.5, a nearby star newly discovered by NASA scientists, there would likely be no such thing as a bathing suit or short shorts. That's because this "brown dwarf" - a star too small to enable nuclear fusion and radiate light - is as cold as the Arctic.

Looks like our home galaxy, the Milky Way, has gone on the ultimate weight-loss program, according to astronomers. According to a new supercomputer simulation, it turns out that the entire mass of our Milky Way galaxy is about half that of the great Andromeda galaxy, our nearest neighbouring spiral galaxy some 2.6 million light-years away from us. Astronomers had long thought the galaxies were twins.

According to modern astronomers, the Orion Nebula is an enormous cloud of gas and dust, one of many in our Milky Way galaxy. It lies roughly 1,300 light-years from Earth. At some 30 to 40 light-years in diameter, this great big nebulous cocoon is giving birth to perhaps a thousand stars. Much more info at the source!
